Why Lifelock Inc Shares Dropped

Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of LifeLock Inc were getting broken today, falling as much as 11%, and finishing down 7% after a pending Federal Trade Commission investigation was revealed over the weekend.

So what: The identity-theft protection service said in its 10-K filing that it had met with the FTC to discuss whistle-blower claims regarding its marketing practices. In a statement, the company said, "We believe we are in an environment in which there is increased regulatory scrutiny," and that it believes "there has been a recent increase in whistleblower claims made to regulatory agencies."

Now what: A regulatory investigation is never good news, but there's really not enough information in LifeLock's statement to gauge the seriousness of the whistle-blower claims. In 2010, LifeLock paid $12 million to settle charges from the FTC, so it is no stranger to regulatory action.
